A controller may be positioned within an explosion-proof housing in a process control system. The controller may be connected to circuit breakers within the explosion-proof housing via wired communication links, and connected to devices positioned external to the explosion-proof housing via wireless communication links. The wireless communication links may have lower bandwidth than the wired communication links. The controller may include one or more processors and one or more memories storing a set of computer-executable instructions that cause the controller to: receive, from the breakers via the wired communication links, data associated with the operation of the circuit breakers; generate messages based on the data associated with the operation of the circuit breakers; and send, via the wireless communication links, the messages to the devices positioned external to the explosion-proof housing.
